Description of problem:
Configuring a Debian system to talk to Spacewalk via proxy server fails to download packages. 

Version-Release number of selected component (if applicable):
2.2


How reproducible:
Configure Ubuntu client to talk to RHN via proxy server. 


Steps to Reproduce:
1.  Install Spacewalk
2.  Install Spacewalk Proxy
3.  Configure Ubuntu client to talk via Spacewalk Proxy.
3a.  Use the following packages for your Ubuntu clients:   https://launchpad.net/~mj-casalogic/+archive/ubuntu/spacewalk-ubuntu

Actual results:

E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?


Expected results:
Package installation to succeed. 
Installation will succeed if the client is pointed directly at the Spacewalk server.

Further examination of the rhnRepository.py source code:   https://github.com/spacewalkproject/spacewalk/blob/master/proxy/proxy/broker/rhnRepository.py

Shows such code as:   (Line 234) 

            extension = "rpm"
            if isSolarisArch(arch):
                extension = "pkg"

There are other examples. 

So, if its not a Solaris package, it has to be a RPM?     

I know Ubuntu is the OS of choice for lemonade stand vendors, but unfortunately due to reasons beyond my control, we're stuck with it, and would prefer a centrally managed Spacewalk infrastructure using proxies, instead of standalone servers.
